Title: Electrical control device
IPC: G05B11/26
Filed: 1975-01-27
Abstract: 1496693 Automatic control systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Jan 1975 [30 Jan 1974]  3403/75 Heading G3R A pulse width modulated process control signal PBM is produced by an arrangement in which actual and desired values of an unspecified process 1 are expressed as frequency-analogue pulse signals Si, Ss, their difference is obtained and is added to a "carrier" frequency STr, the result S'e being connected to one input of a 2-bit reversible counter 21 and the "carrier" frequency being supplied to the input for the opposite counting direction, the output of the counter comprising the said control signal. In the embodiment the pulse signals are divided at 7 and their difference obtained, and the "carrier" added, in a mixer 9. 13 and 15 are further dividers. Before connection to the counter the carrier is phase shifted at 17 by an amount corresponding to the difference frequency (i.e. the error) obtained at 19. This device converts the difference into a voltage which determines the time constant of a monostable multi-vibrator in 17 which is triggered by the "carrier" pulses; the output of 17 corresponds to the trailing edge of the monostable pulses. The counter 21 effectively compares the phase relationship of its two inputs; since this increases with time for a constant error the effect is of integration, the rate of which can be varied by adjusting the division ratio of 7. The multi-vibrator arrangement provides a proportional term, and a differential term may be added but is not described. The output of 21 is taken from its second stage, which is put into a "1" condition by one signal and "0" by the other. The control signal is applied to a corrective element 23 which may be progressive or switched. In modifications the invention is used with a "subordinate" control loop, in which a second actual value signal is obtained from an intermediate point in the process. In Fig. 4 (not shown) the signal PSM gates a clock frequency to a second reversible counter, the other input to which is a frequency corresponding to the second actual value. This counter is connected to a register, the number in which thus represents the difference between the second actual value and the value of PSM, and is used for digital or analogue control via a conventional P & I controller. In Fig. 6 (not shown) the signal PBM is compared directly with one whose pulse width represents the second actual value, the difference being used for analogue control.
